Okay as discussed in the last post I am still project blocked by a failure on my part to get the TI talking with the GPS.  Undoubtedly something simple but as of yet unknown.

 

I had found mention of someone else having similar issues and getting answers on the forum 43oh site.  It appears that basic browsing and searching without a user account will yield no information so here I will connect to that site.

Here we have the basic view once you have connected and NOT logged in with a user account.  Looks promising!

 

(Well Technically I would think the view would be the same even if you are logged in.)

Here we have the result of trying to go deeper into any of those interesting forums and not having an account.

 

If somewhere it states you need to have an account to view those threads I missed that in my excitement to discover a solution to my problem.  :-)

 

So lets follow the tested advice from on registering and then the site opening up for access!

Ah the basics, time to sign up and get some more emails!

Oddly enough it didn't show it in the cut and paste but you do get a popup saying to check your email and confirm.  So off to my email and clickity click.

Tada.  I am now a registered user and and able to jump into the Energia subforum!  Woohoo!

Let's try doing a search on gps to see if that pulls up what I have been looking for and anyone else experimenting with it.

 

Nope 0 results found.  Hmm...

 

image

 

GSM?  Nope.

 

image

 

By the way, don't be too quick in your search efforts or else you get this!

 

So no go with searching.  Or at least with my new experience to their search options.  I did try using the author option and apply the gentleman's name that was talking about the problem on the other site but couldn't find that either.

 

image

 

So let's start browsing through the forum manually.  Only 1,524 topics available.  :-)

 

 

image

 

Wait what?  Why is this back?  I went to double check something while writing the blog...

 

Ah it seems that it has a super fast auto-logoff.  Sigh...

 

image

 

Not sure if they kick you at an hour or what.  You can see I am the newest member of an hour ago.

 

Okay.  End of the blog for now.  I will need time to browse those 1.5k topics.  :-)

    I'll do a check of the program you posted.

     

    I've got a bus pirate (useful when you want to do a quick test of a protocol)

    image

     

    I've removed the TX and RX jumpers from the LaunchPad so that there's no contention between USB and UART.

    (also have to download energia - it's been a while since I used it - a laptop ago image )

    Even just receiving the NMEA strings from the GPS would be great!  :-)

  • in reply to jkutzsch

    Thanks. I'll try to see if that communication receives correctly from a 9600 baud UART.

    This seems to be an input only program, it doesn't send data to the GPS ...

    Here is the example Energia code that the provide:  Energia Reference - Tutorials

     

    /*

      Serial Event example

     

      When new serial data arrives, this sketch adds it to a String.

      When a newline is received, the loop prints the string and

      clears it.

     

      A good test for this is to try it with a GPS receiver

      that sends out NMEA 0183 sentences.

      This example code is in the public domain.

     

    */

     

    String inputString = ""; // a string to hold incoming data

    boolean stringComplete = false; // whether the string is complete

     

    void setup() {

      // initialize serial:

      Serial.begin(9600);

      // reserve 200 bytes for the inputString:

      inputString.reserve(200);

    }

     

    void loop() {

      // print the string when a newline arrives:

      if (stringComplete) {

      Serial.println(inputString);

      // clear the string:

      inputString = "";

      stringComplete = false;

      }

    }

     

    /*

      SerialEvent occurs whenever a new data comes in the

      hardware serial RX. This routine is run between each

      time loop() runs, so using delay inside loop can delay

      response. Multiple bytes of data may be available.

    */

    void serialEvent() {

      while (Serial.available()) {

      // get the new byte:

      char inChar = (char)Serial.read();

      // add it to the inputString:

      inputString += inChar;

      // if the incoming character is a newline, set a flag

      // so the main loop can do something about it:

      if (inChar == '\n') {

      stringComplete = true;

      }

      }

    }

    Good luck. If you want me to test out your code (I don't have the GPS module but have a 432 and can snoop serial coms), just ask what you want to have checked.

    Your project is worth having live. Let's try to make it happen.
